Based on the following story, continue the story by writing two paragraphs, paragraph 1 beginning with "A few weeks later, I went to the farm again. " and paragraph 2 beginning with "I was just about to leave when the hummingbird appeared."respectively with 150 words. I was invited to a cookout on an old friend's farm in western Washington. I parked my car outside the farm and walked past a milking house which had apparently not been used in many years.A noise at a window caught my attention,so I entered it. It was a hummingbird,desperately trying to escape. She was covered in spider-webs and was barely able to move her wings. She ceased her struggle the instant I picked her up. With the bird in my cupped hand, I looked around to see how she had gotten in. The broken window glass was the likely answer. I stuffed a piece of cloth into the hole and took her outside,closing the door securely behind me. When I opened my hand, the bird did not fly away; she sat looking at me with her bright eyes.I removed the sticky spider-webs that covered her head and wings. Still, she made no attempt to fly.Perhaps she had been struggling against the window too long and was too tired? Or too thirsty? As I carried her up the blackberry-lined path toward my car where I kept a water bottle, she began to move. I stopped, and she soon took wing but did not immediately fly away. Hovering,she approached within six inches of my face. For a very long moment,this tiny creature looked into my eyes, turning her head from side to side. Then she flew quickly out of sight. During the cookout, I told my hosts about the hummingbird incident. They promised to fix the window. As I was departing, my friends walked me to my car. I was standing by the car when a hummingbird flew to the center of our group and began hovering. She turned from person to person until she came to me. She again looked directly into my eyes, then let out a squeaking call and was gone. For a moment, all were speechless. Then someone said, “She must have come to say good-bye.”

根据以下要求编写一个python程序1. Description Ship of Fools is a simple classic dice game. It is played with five standard 6-faced dice by two or more players. - The goal of the game is to gather a 6, a 5 and a 4 (ship, captain and crew) in the mentioned order. - The sum of the two remaining dice (cargo) is preferred as high as possible. The player with the highest cargo score wins the round. Example: - In the first round turn, if a player rolls 6 4 3 3 1 (note we five dice at the beginning), the player can bank the 6 (ship), but the rest needs to be re-rolled since there is no 5. - In the second round turn, if the player rolls 6 5 4 4 (four dice, since the 6 from last turn is banked), the player can bank the 5 (captain) and the 4 (crew). The player has three choices for the remaining 6 and 4. The player can bank both and score 10 points, or re-roll one or two of the dice and hope for a higher score. - In the second round turn, if the player instead rolled 4 4 3 1, all dice needs to be re-rolled since there is no 5.程序需要包含一下几个类.The division of responsibility between the different classes is as follows. - Die: Responsible for handling randomly generated integer values between 1 and 6. - DiceCup: Handles five objects (dice) of class Die. Has the ability to bank and release dice individually. Can also roll dice that are not banked. - ShipOfFoolsGame: Responsible for the game logic and has the ability to play a round of the game resulting in a score. Also has a property that tells what accumulated score results in a winning state, for example 21. - Player: Responsible for the score of the individual player. Has the ability, given a game logic, play a round of a game. The gained score is accumulated in the attribute score. - PlayRoom: Responsible for handling a number of players and a game. Every round the room lets each player play, and afterwards check if any player has reached the winning score.
